Determination of chromium in estuarine waters by catalytic cathodic stripping voltammetry using a vibrating silver amalgam microwire electrode

► A silver amalgam microwire is used for voltammetry of Cr. ► The sensitivity is sufficient to determine Cr in estuarine seawater. ►The wire electrode has potential for use in a flow cell. ► The sensitivity for Cr is less than using the mercury drop electrode.
